We're in the heart of summer in Europe, where extreme heat has spiralled into out-of-control wildfires across the Mediterranean, leading thousands to flee their homes.

Previously on Inside Science we've looked at how and why temperatures are soaring across the globe. Now we're homing in on one of the most visible effects of that.

First, BBC climate and science reporter Georgina Rannard paints a picture of the link between these fires and climate change.

Next up we hear from Professor Stefan Doerr, director of the Centre for Wildfire Research at Swansea University, on whether Europe is prepared for a future where these blazes are more frequent and intense.

Another effect of climate change you might have heard about this week is the potential collapse of the Gulf Stream. Georgina explains why leading researchers have reservations about the science behind that claim.

We investigate a sometimes overlooked and under-reported source of pollution: particles from vehicle tyres. Dr Marc Masen from Imperial College London tells us about the impact they’re having on our health.

And pollution from tyres is affecting flora and fauna too. Dr Paul Donald, senior researcher at Birdlife International, explains how vehicles on our roads have impacted wildlife in the environment.

Finally, from four wheels to two wheels! Geneticist and body weight scientist Dr Giles Yeo is cycling from Land's End to John O'Groats with two glucose monitors on his arm. He tells us what he's hoping to learn.
